Einstein’s light-bending by single far-off star detected

Famous effect of general relativity provides accurate mass of distant white dwarf

solar eclipse

SEEING BEYOND This 1919 solar eclipse proved that the sun’s gravity can bend spacetime to make other stars’ positions appear shifted. Now astronomers have seen the same effect with distant stars.

For the first time, astronomers have seen a star outside of the solar system bend the light from another star.
